一种基于线扫描的受损一维条形码识别方法

Accurate Identification Method of Damaged One-dimensional Barcode Based on Line Scan

针对受损情况下的一维条形码识别问题,基于线扫描技术提出一种准确、稳定、高效的识别方法。分析了一维条形码EAN码制的解码原理以及用线扫描方式处理一维条形码信息的过程;根据一维条形码出现的污点、划痕、弯曲等受损情况,设计了对应的算法,并且应用线扫描技术完成解码;最后,采集了1000张一维条形码实验样本验证识别方法的准确性。结果表明:该方法能有效应对受损情况下的解码问题,且解码成功率维持在了较高水平;其中,受一维条形码弯曲程度的影响,弯曲样本的解码成功率为88%,略低于污点样本的95%以及划痕样本的91%;基于线扫描技术的受损一维条形码识别方法具有较强的鲁棒性。

Aiming at the problem of one-dimensional barcode recognition under damaged condition,an accurate,stable and efficient identification method based on line scan technology is proposed.Firstly,the decoding principle of EAN code system and the process of processing one-dimensional barcode information by line scanning are analyzed.According to the characteristics of the damaged barcode,the corresponding algorithm is designed,and the line scan technology is applied to complete the decoding.In order to verify the accuracy of the recognition method,1000 samples of one-dimensional barcode are collected.The results show that the method can effectively deal with the decoding problem under damaged conditions,and the decoding success rate is maintained at a high level.Affected by the bending degree of one-dimensional barcode,the decoding success rate of curved samples is 88%,which is slightly lower than 95%of stain samples and 91%of scratch samples.The experimental results show that the damaged one-dimensional barcode recognition method based on line scanning technology has strong robustness.
